From a completely disassembled model with one hand and foot attached by nylon cord, to Sam the Super Skeleton – completely put together on a stand with a totally versatile vertebral column, significant muscle origins and insertion points, numbered bones and flexible ligaments – anatomical human skeletal designs are ideal teaching tools.
The human skeletal system, with its 206 bones, is a marvel of nature, enabling the body complete range of motion through 360 degrees on all aircrafts. Not just does this assemblage of bone, ligament and muscle enable us to dance, run, jump and pivot, however the insides of bones include a compound (marrow) that enables the body to make new red cell. Bones likewise save important minerals, like calcium, which is essential not only in maintaining bone strength and health but in transforming electrical signals from the brain into electrochemical signals that own the human nerve system and make activity possible at the most elemental level.
From the thigh, the longest bone in the body, to the stirrup inside the ear, bones are the ‘framework’ for life. Some parts of the body, like the hand, are extremely articulated, including 26 bones joined by ligaments and muscles that enable us to do whatever from develop skyscrapers to perform the most complex surgical treatment. Humans, in reality, are the only members of the animal kingdom whose development has permitted the hand to rule the planet.
Without an understanding of the human skeleton, no one – from grade school student to medical resident – can fully comprehend the miracle of movement. This is why skeletal models are so essential. Taken apart designs, from half skeletons (based on the sagittal airplane) to full skeletons, allow students of any ages to study the formation of specific bones and their relationship to adjacent structures. Put together designs, on stands, range from a basic, skeletal model to more complicated models revealing muscles or ligaments at both origin and insertion point along one side of the sagittal airplane. These latter models are perfect for sports medication specialists, and allow therapists to demonstrate how sprains, stress and injuries can affect instant and future sports efficiency.
A plain skeleton on a stand is a beneficial tool for high school and secondary school human anatomy classes, and miniature designs will supply a wealth of mentor home entertainment for elementary school teachers and students.
Versatile skeletal models, with spines that enable mimicry of any human posture, are ideal tools for osteopaths or orthopedic cosmetic surgeons. These models, when placed in a position that shows osteoporotic posture, for example, stay as configured, allowing doctors to show their clients how pathological postures occur and what can be done to correct them. In both basic and exceptional models, these models move through the whole variety of skull and neck positions, and spine nerve exits and vertebral arteries are shown as dorso-lateral disc prolapses in between the third and 4th back vertebrae in the mid-back. Both models also have teeth, a tripartite skull, easily detachable limbs, and the weight of the 2nd model is almost identical to that of a human skeleton.
The paradigm, nevertheless, is a physiological skeleton which reveals the complete series of motion of the arms, for instance, through abduction, adduction, anteversion and retroversion. This clinical design likewise permits demonstration of the limited motion of the iliosacral and sacrococcygeal joints in the lower spinal column. Completely versatile and made from unbreakable plastic, this practical skeletal model is perfect for all instructional circumstances where a complete comprehension of skeletal motion is vital.
